There's no magic in dealing with Target's information security breach but there are some common-sense approaches to keep money from leaking out of your bank account.

Ohio University IT Communications Manager Sean O'Malley advises to do the things you should be doing regardless of a security issue:

  • Keep an eye on your statements.  Look at purchased items to make sure they're things you have purchased or authorized.
  • Know who you're dealing with. 

In Target's case O'Malley says it's a reputable business so those who used cards there already knew the company but in some cases businesses aren't as well known. 

In those cases he advises caution.

Target's pre-Christmas data breach compromised as many as 70 million customer accounts, far more than the earlier estimate of 40 million Target had said were affected.


Target says that personal information – including phone numbers and email and mailing addresses – was stolen from as many as 70 million customers in its pre-Christmas data breach. That was substantially more customers than Target had previously said were affected.

The chain also cut its fourth-quarter adjusted earnings forecast and outlook for a key sales barometer.

Target had announced in December that about 40 million credit and debit cards may have been affected by a data breach that happened between Nov. 27 and Dec. 15 – just as the holiday shopping season was getting into gear.

The retailer said Friday that the personal information stolen is not a new breach, but was discovered during its ongoing investigation.

Target Corp.'s stock fell in Friday premarket trading.
